Published Workflows
Objective: Construct and apply orthoflavivirus pseudoviruses as a safer platform for antiviral research on highly pathogenic arthropod-borne orthoflaviviruses.
Why it works: The abstract states that pseudoviruses are replication incompetent, reducing biosafety risk, and that construction leverages the host cell secretory pathway to mimic natural viral assembly and maturation.

The abstract states that construction primarily relies on multi-plasmid co-transfection of viral replicons and structural protein expression vectors. It also depends on the host cell secretory pathway to mimic viral assembly and maturation.; relies on multi-plasmid co-transfection of viral replicons and structural protein expression vectors; leverages the host cell secretory pathway to mimic natural viral assembly and maturation
The abstract notes that pseudoviruses do not completely simulate native viral structures. It also reports batch-to-batch titer variability that can reduce physiological relevance.; incomplete simulation of native viral structures; batch-to-batch titer variability; physiological relevance of findings may be affected
